Great idea for Kevins Kustom Tattoos in New Zealand. Here is some explanation from the agency:
We designed a stamp of the logo in a way that mimics a desirable Celtic tattoo with a phone number for the nearest branch. We then passed it over to the areaâ€™s trendiest nightclub where a stamp is compulsory for entry. Before the end of the evening the target market were not only aware of where to go, but they were branded – literally.
